In laying out a subdivision, the owner shall conform to the provisions of Ch. 236, Wis. Stats., and all applicable ordinances of the Village. In all cases where the requirements of this chapter are different from the requirements of Ch. 236, the more restrictive provision shall apply.
A. 
Streets shall be provided for convenient access to all parcels of land to be created by the subdivision. All streets shall be dedicated to the public, unless in areas outside the corporate limits the town board will permit private streets. Design of private streets shall be in full conformity with this chapter.
B. 
The layout of streets shall conform to the Official Map and Comprehensive Plan.
C. 
In areas not covered by the Official Map or Comprehensive Plan, the layout of streets shall conform to the plan for the most advantageous development of adjoining areas of the neighborhood. Streets shall be designed and located in relation to existing and officially planned streets, topography and natural terrain, streams and lakes, and existing tree growth, public convenience and safety, and in their appropriate relation to the proposed use of land to be served by such streets.
D. 
In general streets shall be laid out in a grid-type pattern to the greatest extent possible. Culs-de-sac shall be avoided except in areas where, in the opinion of the Plan Commission, the shape of the parcel to be subdivided does not lend itself to the use of through streets.
E. 
Streets shall be classified as indicated in this subsection.
(1) 
Arterial streets are those streets which have the greatest importance to the development of the Village and which have a width of right-of-way as shown on the Official Map or of not less than 100 feet for a median-divided roadway nor less than 80 feet for a single roadway. The exact physical width of an arterial street will be determined by the Village Engineer based on street location and anticipated traffic patterns.[1]

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
(2) 
Collector streets are streets of somewhat less importance than major thoroughfares and which have a right-of-way width as shown on the Official Map of not less than 66 feet. Collector streets are the standard Village street and shall have a width of 36 feet from back of curb to back of curb.[2]
[2]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
(3) 
Minor streets are streets designed primarily for access to abutting property and which have a right-of-way width of not less than 60 feet and culs-de-sac not more than 600 feet long that may have a right-of-way width of not less than 60 feet and must be provided with a turnaround at the dead end of not less than 120 feet in diameter. The width of a minor street may be less than the standard for collector streets subject to the approval of the Village Engineer but in no cases shall be less than 28 feet from back of curb to back of curb.
(4) 
Marginal access streets as defined in § 350-8 of this chapter may not be less than 50 feet wide.
F. 
Proposed streets shall be extended to the boundary lines of the tract to be subdivided, unless prevented by topography or other physical conditions, or unless in the opinion of the Plan Commission such extension is not necessary or desirable for the coordination of the layout of the subdivision with existing layout or the most advantageous future development of adjacent tracts. Temporary turnarounds may be required where the street ends at the boundary of a subdivision.
G. 
The grade of arterial streets shall not exceed 6% unless necessitated by exceptional topography and approved by the Plan Commission. Grades of collector streets shall not exceed 10%. The minimum grade of all streets shall be 4/10 of 1%.
H. 
A minimum sight distance with clear visibility, measured along the center line, shall be provided of at least 500 feet on arterial streets, 200 feet on collector streets, and 120 feet on all other streets.
I. 
All changes in street grades shall be connected by vertical curves of a minimum length in feet equivalent to 30 times the algebraic difference in grade for arterial streets and 20 times this algebraic difference for all other streets.
J. 
A tangent of at least 100 feet long shall be introduced between reverse curves and between curves and a street intersection on arterial and collector streets.
K. 
New street names shall not duplicate the names of existing streets, but streets that are continuations of others already in existence and named shall bear the names of the existing streets.
L. 
Reserve strips controlling access to streets shall not be permitted unless this control is definitely placed with the Village under conditions approved by the Plan Commission.
M. 
Where a half street is adjacent to the subdivision, the other half street shall be dedicated by the subdivider.
N. 
Intersections.
(1) 
Property lines at street intersections of arterial streets shall be rounded with a radius of 15 feet or of a greater radius where the Plan Commission considers it necessary.
(2) 
Street jogs with center-line offsets of less than 125 feet shall be avoided. Where streets intersect arterial streets, their alignment shall be continuous.
(3) 
The provisions of Chapter 365, Zoning, § 365-80 of this Code with respect to traffic visibility at street intersections shall also apply here.
A. 
The length, width and shape of blocks shall be such as are appropriate to the locality and the type of development contemplated, but block length in residential areas shall not exceed 1,500 feet nor have less than sufficient width to provide for two tiers of lots of appropriate depth between street lines. As a general rule, blocks shall not be less than 600 feet in length.
B. 
Pedestrian pathways, not less than 10 feet wide, may be required by the Plan Commission through the center of a block more than 900 feet long where deemed essential to provide circulation or access to schools, playgrounds, shopping centers, transportation and other community facilities.
C. 
General considerations with regard to lots are as follows:
(1) 
Size, shape and orientation of lots shall be appropriate for the location of the subdivision and for the type of development contemplated, provided that no residential lot shall be smaller in area than the minimum lot size for the appropriate zone as established by Chapter 365, Zoning, of this Code.
(2) 
Lot dimensions shall conform to the requirements of Chapter 365, Zoning, but in no case shall have a frontage of less than 50 feet at the building line or a depth of less than 100 feet.
(3) 
Depth and width of properties reserved or laid out for commercial or industrial purposes shall be adequate to provide for the off-street service and parking facilities required by the type of use and development contemplated, as required by Chapter 365, Zoning.
(4) 
Residential lots fronting on arterial streets and highways shall be platted with extra depth or designed to alleviate the effect of major street traffic on residential occupancy.
D. 
Corner lots for residential use shall have extra width to permit building setback from both streets, as required by Chapter 365, Zoning.
E. 
Every lot shall abut or face a public street. Lots outside the corporate limits may abut or face a private street, if permitted by the town board.
F. 
Butt lots will be permitted by the Plan Commission only in exceptional cases.
G. 
Side lot lines shall be substantially at right angles to or radial to abutting street lines.
H. 
In case a tract is divided into parcels of more than 1 1/2 acres in area, such parcels shall be so arranged to permit redividing into parcels in accordance with this chapter and with Chapter 365, Zoning.
I. 
Double frontage and reversed frontage lots shall be avoided except where necessary to provide separation of residential development from traffic arteries or to overcome specific disadvantages of topography and orientation.
A. 
Filling of all lots in each subdivision is required to a point not less than one foot below the flood protection elevation for the particular area as determined by procedures specified in Chapter 345, Floodplain Zoning, of this Code.[1]

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
B. 
Areas to be filled shall also include all street rights-of-way and other appropriate areas, such as park and open space lands, so that they bear a reasonable relationship to adjoining properties.
A. 
The following goals and objectives shall apply to stormwater management:
(1) 
To prevent significant loss of life and property due to runoff from any foreseeable rainfall event.
(2) 
To encourage the design of system which minimizes potential erosion and sedimentation problems.
(3) 
To maintain the water quality of the rivers, lakes, streams and ponds.
(4) 
To encourage the design of systems which respond to the need to maintain or enhance groundwater resources, including groundwater quality, except where land stability might be impaired.
(5) 
To encourage the design of systems which will reduce capital and environmental costs to the community.
B. 
The proposed development shall not increase stormwater runoff (peak) from that which would have resulted from the same storm occurring over the site with the land in its natural undeveloped state, for storms of a twenty-four-hour duration and all reoccurrence intervals of less than or equal to 100 years. "Land in its natural undeveloped state" shall mean land which has runoff characteristics equivalent to runoff curve numbers (CN) of 30, 58, 71 and 78 for Hydrologic Soil Groups A, B, C and D, respectively.
C. 
Determination of storm volumes shall be computed by established procedures equivalent to and calibrated against that procedure promulgated by the United States Soil Conservation Service in its National Engineering Handbook or the technical publication titled "Urban Hydrology for Small Watersheds, TR-55" and accepted by the Village Engineer.
D. 
Stormwater peaks and volumes shall be addressed either through on-site detention, retention, infiltration, or a combination. It is the intent of these provisions to encourage on-site detention and infiltration to the greatest extent possible.
A. 
Adequate easements shall be provided and dedicated on each side of all rear lot lines, and on side lot lines, and along front lot lines where necessary, for the installation of storm and sanitary sewers, gas, water mains, electric lines, telephone and cable television communication lines.
B. 
Easements for electric lines, telephone, gas and cable television communication lines shall be noted as "Utility Easements" on the final plat or certified survey map.
C. 
All easements for storm and sanitary sewers, water mains, pedestrian walks and other public purposes shall be noted on the final plat or certified survey as "Public Easement for" followed by reference to the use or uses for which they were intended.
D. 
Where a subdivision is traversed by a watercourse, drainageway, channel, or stream:
(1) 
There shall be provided a stormwater easement or drainage right-of-way conforming substantially to the lines of such watercourse and such further width or construction, or both, as will be adequate for the purpose and as may be necessary to comply with this section; or
(2) 
The watercourse, drainageway, channel, or stream may be relocated in such a manner that the maintenance of adequate drainage will be assured and the same provided with a stormwater easement or drainage right-of-way conforming to the lines of the relocated watercourse and such further width or construction, or both, as will be adequate for the purpose and may be necessary to comply with this chapter.
E. 
Wherever possible, it is desirable that drainage be maintained by an open channel with landscaped banks and adequate width for maximum potential volume of flow. In all cases, such watercourse shall be of a minimum width established at the high-water mark or, in the absence of such specification, not less than 30 feet.
